Answer:
<u><em>There is not enough information to know if there is a statistically significant difference in the number of children per family between the three countries.</em></u>
Step-by-step explanation:
There are other important information that are necessary in order to reach a decisive conclusion. This includes not just the f value only, but the alpha value, f critical value and the p-value after conducting the one way ANOVA.
Since we do not have information about the p value, as well as the alpha value there is no way to compare the effects of all the variables.
Therefore, no decision can be made by the Pediatrician without knowing what the p value is and the apha value is.
The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
x = 14.5
m∠DEA = 39.5°
m∠AEB = 140.5°
Solution:
Sum of the measures of adjacent angles in a straight line is 180°.
m∠DEA + m∠AEB = 180°
The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
⇒ m∠DEA + m∠AEB = 180°
⇒ (x + 25)° + (9x + 10)° = 180°
⇒ x° + 25° + 9x° + 10° = 180°
⇒ 10x° + 35° = 180°
Subtract 35° from both sides of the equation.
⇒ 10x° = 145°
⇒ x° = 14.5°
⇒ x = 14.5
m∠DEA = (9x + 10)°
= (9(14.5) + 10)°
m∠DEA = 39.5°
m∠AEB = (x + 25)°
= (14.5 + 25)°
m∠AEB = 140.5°
Answer:
x = 0
Step-by-step explanation:
27 - 3x = 3x + 27
- 3x - 3x = 27 - 27
- 9x = 0
x = 0
I'm sending you two screenshots of the explanation I hope this helps.
